BV513 Getting Started

Resources

The BV513 is a small PCB that is a carrier for the PIC32 microcontroller, the non-cut down version comes with a micro SD Card holder and a USB interface. ByPic firmware is installed by default. The built in USB interface uses the FTDI virtual COM port. This chip is chosen because of its widespread use. It is built into Linux and has drivers for most of the popular operating systems.

COM Port Driver

The BV513_V2 uses the FTDI chip and this is built into most operation systems so should be recognised as a COM port without any difficulty.

To get connect to a USB to serial device, get started with the IDE and see how things work, follow this link.

Connecting a second SD Card Holder

ByPic will recognise any SD Card that is connected using a suitable holder. The connector to use is the end connector. The instructions here are for any generic holder that can be used. A typical SD Card holder can be found here and will be used in this example.

The pins are marked on the PCB as shown in the table.

Only 6 connections are required, in case you are wondering, MISO means Master In Slave Out and MOSI means Master Out Slave In. In this case the master is the BV513 and the slave is the SD Card holder.

After inserting an SD Card and pressing reset we can see that the card has been recognised as Card 1. If this is a BV513_V2 then Card 0 would be the on board micro SD Card holder.
